===================================================================
V1113 Cyg [UGSU, 14p - <17p]
============================
Gary Poyner, Birmingham, UK reports an outburst detection of this
little studied cataclysmic variable. Confirmative observations would be
appreciated.
1995 04 19.028 UT, 13.7 (G. Poyner, 0.40-m refl., comp.star 13.6 Kato);
13.7
During the September 1994 outburst of V1113 Cyg, Taichi Kato (Ouda Station,
Kyoto University, Japan) made V-band CCD photometry observations, that
clearly revealed the presence of superhumps in the lightcurve. The super-
humps had an amplitude of 0.23 mag (V) and a period a bit shorter than
2 hours [CVC 15]. Apart from this professional observation, we could trace
no further information on V1113 Cyg.
V1113 Cyg was last seen in outburst on January 31, 1995 by L. Szentasko,
Hungary (unconfirmed observation), at mag 14.0 [CVC 27].
AL Com [UGWZ, 12.8v - 22v]
==========================
Further to the photometric summary published in CVC 34, the table
below lists additional outburst observations of AL Com. We express
our sincere thanks to the many amateur and professional astronomers,
who reacted on CVC 33 & 34, by submitting supplementary material on
this UGWZ-type dwarf nova.
